Posttest: Behaviours | 14 | 1.328 | 0.756 | 1.901 | 402.12 | 13 | < .001 | 97% |
Posttest: Knowledge | 16 | 1.288 | 0.898 | 1.679 | 387.23 | 15 | < .001 | 96% |
Follow-up: Behaviours | 6 | 1.795 | 0.672 | 2.919 | 236.48 | 5 | < .001 | 98% |
Follow-up: Knowledge | 9 | 0.762 | 0.473 | 1.050 | 41.97 | 8 | < .001 | 81% |
k: number of studies. d_{+}: mean effect size. d_{l} and d_{u}: lower and upper confidence limits of the 95% confidence interval around the mean effect size. Q: heterogeneity statistic. df: degrees of freedom. I^{2}: heterogeneity index.
